Ryobi 48V Lawn Mower Lithium Battery Replacement
Canbat Ryobi 48V lithium conversion kits are designed for Ryobi 48V ride-on mowers originally equipped with lead-acid batteries. They replace the mower’s 48V lead-acid battery bank with a lighter, longer-lasting LiFePO4 battery system built around the Canbat GC2-30-48 module — a sealed 48V battery with an integrated smart BMS, paired with a matched 48V lithium charger.
Each Canbat GC2-30-48 module is a complete 48V lithium battery system designed to replace the original four-battery lead-acid bank in Ryobi 48V ride-on mowers. The 30Ah kit uses one module for a lighter, lower-cost lithium upgrade, while the recommended 60Ah kit uses two modules in parallel for longer runtime, stronger output headroom, and fewer recharge breaks.
This gives Ryobi owners a cleaner lithium upgrade path: lighter weight, longer service life, no lead-acid maintenance, and a purpose-built 48V system supplied with a matched lithium charger and wired fuel gauge monitor.
Choose Your Ryobi 48V Lithium Kit
Both kits are built on the same GC2-30-48 LiFePO4 module. The difference is how many modules you run — which sets your runtime and your output headroom under load.
48V 60Ah Ryobi Lithium Kit
Two GC2-30-48 modules in parallel · dual-battery system
- Double the runtime of the single-battery kit
- Increased output headroom — two modules share the load in parallel
- Recommended for most Ryobi 48V riding mowers, larger lawns, thicker grass, and hills
- Includes a heavy-duty parallel busbar to link both modules
- Supplied with a matched 48V lithium charger and wired fuel gauge monitor
48V 30Ah Ryobi Lithium Kit
One GC2-30-48 module · lower-cost single-battery option

One 48V Lithium System Replaces Four 12V Lead-Acid Batteries
Most Ryobi 48V riding mowers are powered by four 12V lead-acid batteries wired in series to create a single 48V system. Canbat’s conversion kits replace that entire four-battery bank with one 48V lithium system: a single GC2-30-48 module for the 30Ah kit, or two modules connected in parallel for the 60Ah kit.
You do not need four separate lithium batteries. Each Canbat module already outputs 48V on its own — adding a second module increases capacity and output headroom, not voltage.
30Ah vs 60Ah: More Than Just Runtime
The 60Ah kit is not simply a bigger fuel tank. Because it runs two modules in parallel, it also increases the output headroom available to the mower — the headroom that matters in thick grass, on hills, and on larger machines. That’s why it’s our recommendation for most Ryobi 48V riding mower conversions.
| 48V 30Ah Kit | 48V 60Ah Kit — Recommended | |
|---|---|---|
| Configuration | 1 × GC2-30-48 module | 2 × GC2-30-48 modules in parallel, with busbar |
| Total capacity | 30Ah (1,536Wh) | 60Ah (3,072Wh) |
| Runtime | Suited to smaller lawns and lighter mowing sessions | Double the stored energy of the 30Ah kit, for longer sessions and fewer recharge breaks |
| Output headroom | Single-module output — suited to lighter, steady loads | Two modules share the load in parallel, increasing available output headroom for hills, thick grass, and larger machines |
| Best for | Lighter-duty mowing, smaller lawns, flatter terrain | Most Ryobi 48V riding mower conversions |
Runtime varies by mower model, deck size, grass height, terrain, mowing speed, and battery condition.
GC2-30-48 Battery Dimensions
Use these dimensions to compare the GC2-30-48 module with your mower’s battery area. The Canbat lithium module replaces the full 48V lead-acid battery bank, but it does not need to sit in the exact same layout as the original four batteries. Depending on the Ryobi model, the module can be positioned in the battery compartment in the orientation that gives the cleanest fit, as long as it is securely mounted and protected from movement during mowing, transport, or vibration.
| Length | 260 mm / 10.2 in |
| Width | 180 mm / 7.08 in |
| Height | 283 mm / 11.14 in |
| Weight | Approx. 33 lbs / 15 kg |
| Case size | Group GC2 |
For the 60Ah kit, two GC2-30-48 modules are used in parallel. Plan space for both modules and the parallel busbar, with the batteries positioned securely in the mower’s battery area.

Model numbers and configurations can vary by production year and region. Use this table as a guide, then confirm your mower is a Ryobi 48V lead-acid ride-on model and compare the battery dimensions with your available battery area before ordering. Final fitment depends on your mower’s tray layout, wiring layout, and how the batteries are positioned and secured during installation.
Installation Fitment Note
These kits are designed for Ryobi 48V lead-acid ride-on mowers, including models such as the RY48110, RY48111, RY48112, RY48113, RY48130, and RY48140. The Canbat lithium module replaces the mower’s 48V lead-acid battery bank, but it does not need to sit in the exact same layout as the original four batteries.
Final positioning depends on the mower’s battery area and the installer’s preferred layout. The module can be positioned in the orientation that gives the cleanest fit, as long as it is securely mounted and protected from movement during mowing, transport, or vibration. Some installations may require tray adjustment, repositioning, tie-downs, brackets, or other securing hardware.
These kits are designed for Ryobi 48V lead-acid ride-on mowers only. They are not intended for Ryobi 40V, 80V, or other non-48V platforms.
Please review the installation fitment note before ordering. Opened or installed electrical products may be subject to Canbat’s return policy.
What’s Included — and What May Be Required
Included with your kit
- 48V LiFePO4 battery — one module (30Ah kit) or two modules (60Ah kit)
- Matched 48V lithium charger
- Wired fuel gauge battery monitor
- Heavy-duty parallel busbar (60Ah kit)
- Canbat technical support for fitment, setup, and troubleshooting questions
Not included — may be required depending on your model
- Model-specific tie-downs or hold-down hardware
- Custom brackets or tray adjustment hardware
- Additional wires, ring terminals, or model-specific hardware for your mower’s particular harness
- 48V-to-12V DC-DC converter for lights or accessory circuits
- Dash or panel opening adjustment, if the supplied fuel gauge is larger than the factory gauge
- Installer labour, if you prefer professional installation
Requirements vary by mower model, so we keep these items separate rather than including hardware that may not fit every installation. Having the right items on hand makes for a smooth one-session install.
Before First Charge & First Start
Modules may ship switched off for transport safety, and the mower or charger may show no response until the battery power switch is on.
- Switch the battery ON before charging or testing.
- Use the matched 48V lithium charger supplied with the Canbat kit.
- Confirm all battery connections are secure and that polarity is correct before charging or operating the mower.
- After charging, test the mower under light load before normal mowing.
The Fuel Gauge Monitor
The fuel gauge is a dash-mounted display that shows your battery’s state of charge while you mow — remaining charge at a glance. It is a wired monitor, not a Bluetooth feature, and it must be wired with correct polarity and secure connections. The supplied gauge may have a larger diameter than the factory Ryobi gauge, so some installations may require enlarging the existing dash or panel opening to fit it.
Gauge shows no display? Check, in order:
- The battery power switch is ON
- Wiring polarity is correct
- The main connector is fully seated in the correct orientation
- Ring terminals are tight and connected securely
Lights & Accessory Circuits
Some Ryobi models power their headlights or accessories by tapping 12V from one battery in the original four-battery lead-acid bank. After converting to a single 48V lithium system, that tap point no longer exists — so accessory circuits may need to be powered differently.
Depending on your mower and accessories, a 48V-to-12V DC-DC converter may be required to run lights and 12V accessories correctly.
Frequently Asked Questions
Do I need four lithium batteries to replace my four 12V lead-acid batteries?
No. Your four 12V batteries are wired in series to make one 48V system. Each Canbat GC2-30-48 module outputs 48V on its own, so one module (30Ah kit) or two modules in parallel (60Ah kit) replaces the entire bank.
What is the difference between the 30Ah and 60Ah Ryobi kits?
The 60Ah kit uses two of the same modules in parallel, connected with a supplied busbar. That doubles the capacity for longer runtime, and increases the available output headroom because two modules share the load. The 30Ah kit is a lower-cost single-module option for lighter-duty use.
Is this a drop-in replacement?
From a system-voltage standpoint, yes — the kit is designed to replace the mower’s 48V lead-acid battery bank. Physically, lithium modules have different case dimensions than the original lead-acid batteries, so some installations may require repositioning, tray adjustment, or additional securing hardware. The main consideration is physical fitment and secure mounting, not voltage matching.
Will it fit my Ryobi mower?
The kits are designed for Ryobi 48V ride-on mowers originally equipped with lead-acid batteries. Because the lithium case dimensions differ from the originals, fit in the battery compartment varies by model — some installs are straightforward, others need repositioning or extra securing hardware. If your model has an unusual tray or wiring layout, contact us and we can help.
Can I install the battery on its side?
Side mounting may be possible in some installations, but customers should contact Canbat before mounting the battery on its side. This can help with fitment in trays where an upright position is tight. Whatever the orientation, the module must be securely fastened so it cannot move during mowing, transport, or vibration.
Does the kit include all wires and tie-downs?
The kit includes the core battery system components. Model-specific items — such as tie-downs, brackets, additional wires, ring terminals, and accessory converters — are not included because requirements vary by mower model and battery compartment.
Why does my charger show red and green at the same time?
This often means the charger is not detecting an active battery — usually because the battery switch is OFF or the connection is incomplete. Confirm the power switch is ON (modules ship switched off for transport) and that the terminal connections are secure, then reconnect the charger before assuming anything is defective.
Can I use my original Ryobi lead-acid charger?
No. These kits are supplied with a matched 48V lithium charger, and you should use the charger provided with the Canbat lithium kit. The original Ryobi lead-acid charger is designed for the original lead-acid battery bank and should not be assumed suitable for LiFePO4 batteries.
Does the battery include Bluetooth?
No. Battery monitoring for these kits is provided through the wired fuel gauge display — not through Bluetooth or a phone app.
Can I still use my mower’s lights after conversion?
Usually yes, though some models need an extra component. Ryobi models that tap 12V off one of the original lead-acid batteries for lights lose that tap point after conversion, so a 48V-to-12V DC-DC converter (not included) may be required.
What if I’m not comfortable installing it myself?
A qualified technician or shop comfortable with low-voltage DC battery wiring can complete the conversion, and our support team is available to help you or your installer with fitment, setup, and troubleshooting questions.
